prep.|ain't;不是（等于was not）
"wasn't"是英語中常見的縮略形式，由"was not"通過省略字母組合而成。該詞主要用于否定語境中，表示過去時間中某事物或狀态的不存在或未發生，屬于标準英語語法中的否定結構。
在語法功能上，"wasn't"作為系動詞"was"的否定形式，適用于第一人稱單數（I）和第三人稱單數（he/she/it）的主語。例如："She wasn't at the meeting yesterday"（她昨天沒參加會議）。根據劍橋詞典的釋義，這類縮略形式在口語和非正式書面語中使用頻率較高，但在正式寫作中建議使用完整形式"was not"。
發音方面，"wasn't"的國際音标标注為/ˈwʌzənt/，其中"-sn't"的輔音連綴發音需要注意舌尖抵住上齒龈的爆破過程。牛津英語詞典指出，這類縮略詞的發音保留了原始詞"was"的核心元音，同時通過鼻腔爆破完成"n't"的發音。
在語義層面，該詞既可用于表達客觀事實的否定（如"The answer wasn't correct"），也可用于委婉拒絕或表達主觀判斷（如"I wasn't aware of the change"）。柯林斯高級英語詞典特别強調，當與進行時态結合時，該詞能構建動态否定語境，例如："He wasn't working when I called"。
需要注意的常見錯誤包括：誤将"wasn't"用于複數主語（正确應為"weren't"），以及在倒裝疑問句中錯誤拆分（正确形式為"Wasn't she...?"）。根據朗文當代英語詞典的語法指南，這類錯誤會破壞句子的時态一緻性。
"Wasn't" 是英語中常見的縮寫形式，以下是其詳細解析：
Hewasn't at home yesterday.（他昨天不在家）
The catwasn't hungry.（那隻貓不餓）
Shewasn't happy with the result.（她對結果不滿意）
Iwasn't a teacher ten years ago.（十年前我不是老師）
Hewasn't reading a book when I called.（我打電話時他沒在讀書）
The meetingwasn't postponed.（會議未被推遲）
The weatherwasn't sunny yesterday.（昨天天氣不晴朗）
Your hairwasn't long then, but now it is.（那時你頭發不長，但現在很長）
The partywasn't fun.（那個聚會沒意思）
"Hewasn't what I wanted, what I thought, no."（他并非我心中所想之人）
Wasn't 是英語中表達過去否定狀态的核心詞彙，需結合語境選擇正确的語法結構。掌握其與didn't 的區别及適用場景，可顯著提升語言準确性。
